The top is a major red flag, though I think we all already know that pretty well. If I was taking this manhwa seriously, which I am not, I'd talk about sexual abuse and sh**, but whatever, let's say I'm colourblind.
But, what annoys me the most is the MC. At first, I really liked him, he was witty, quite smart, very determined and didn't take bullshit from anyone. He was also strong. And that's what I have a problem about. He was supposed to be this really da** strong guy who has done boxing for 5 years and can beat anyone up, and you're telling me that he seriously can't push away a guy who sits behind his desk all day? That's bullshit. They just needed a reason for them to start making out. And alright, sure, make out if you want. But there are a thousand better ways to initiate it.
I dunno, maybe it's just this relationship dynamic that's so off-putting for me. Cuz it started with a tough, witty bottom and a conceited but charming top and rn it's a weak-a** annoying bottom and a top who forces himself on him.
Also, somebody please fix the translation

My toxic trait is I start toxic-looking manhwas and then I'm mad when they are toxic
